Trying to do an insulation test on my ring main! As it is not feasable to dissconnect all appliances from sockets, I have connected the phase and neutral together then testing them to earth. For some reason it wont let me! It wont even let me test between cpc and neutral. Any ideas!
Im new to testing just about to take my 2391 inspect and test!
